CAUTION
Thin-wall insulation is not recommended for higher soldering iron temperatures and for gauges larger than AWG 20 Stripping of Tape-Wrapped-Sintered (TWS) PTFE insulation is generally difficult on automatic high-speed machines, more so, for thin-wall finer sizes ADVANTAGES OF PTFE INSULATION
PHYSICAL/CHEMICAL
- Inert to practically all chemicals even at elevated temperatures
- Excellent Resistance to Ultra-Violet radiation and stress-cracking
- Non-contaminating, Non-toxic and bio-compatible
- Resistant to fungus and mould growth
HIGH TEMPERATURE
- Excellent thermal stability — suitable for use from -200°C to 260°C
- Fire (flame) proof
- Soldering iron resistant and suitable for high density wiring
ELECTRICAL
- Suitable for very wide frequency range (DC to above 10,000 MHz) over wide temperature range
- Lowest dielectric constant (2.1)
- Lowest dissipation factor (below 0.0003)
- Highest volume and surface resistivities (in Teraohms)
- Corona Resistance is fair (CR PTFE is available for severe corona conditions)
MECHANICAL
- Smaller size, lighter weight and much higher reliability
- Cold-flow and cut-through resistance — fair (good mechanical strength)
- Excellent flex-life
